BY ATTO EY UNITED STATES PATENT OFFICE,

EDWARD HANDLER, 0F NEWARK, NEW JERSEY.

MUSIC-LEAF TURNER.

To all whom it may concern:

Be it known that I, EDWARD HANDLER, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful In'iprovements in Music-Leaf Turners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being-had to the accompanying drawings, and to figures of reference marked thereon, which form a part of this specification.

This invention relates to a music leaf turner which is adapted to be detachable on a suitable music support, such as a piano or a music stand, and is designed to collapse so that it can be easily carried about, and one that can be easily set up and secured in place and have its parts opera tively connected.

The invention is designed for turning sheets of music and is illustrated and is particularly adapted for use with music having a single insert leaf, which is the usual type of music now employed, the .device beingadapted to operate by a pressure of the finger on a suitable tripping device.

The invention further consists in a device of this kind which is simple to operate and which can be easily kept in order and is not apt to fail in its operation because it is ex tremely simple in its construction.

The invention is illustrated in the accompanying drawing, in which- Figure 1 is a View of the music leaf turner set up and showing a piece or sheet of music in dotted outline. Fig. 2 is a top view of the music leaf turner showing the device when it is collapsed. Fig. 3 is a front view partly broken away, and Fig. 4 is a side view of the spring-actuated turning means and a cap covering the same. Fig. 5 is a detail view showing a clamp used in attaching the turner to one type of support, such as the front panel of a piano, and Fig. 6 is a similarview of a modified form of clamp for attaching the device to a different type of front panel.

A number of different embodiments can be used with this invention, and changes can be made in the disposition and proportion of the parts and in the details of the construction, but the preferred form of de- Specification of Letters Patent.

vice is illustrated in the drawing above described.

The music leaf turner consists of a frame having side bars 10 and 11 and a top bar 12. The side bars are hinged at 13 to the top bar, one bar at its pivotal end 13 having a washer or a suitable device 1 1, the other side bar having a washer or collar 15 or a similar device for permitting the side bars 1.0 and 11 to swing in different planes so that they can fit alongside of each other when swung to the position shown in Fig. 2. In this figure the side bars are illustrated as both swinging to the rear of the top bar, although this particular disposition is not essential. To the top bar is secured a suitable pin 16 which acts as a pivot for the arm 17 the arm swinging on or with the pin and having on its end a suitable clip 18, the clip having the fingerpieces 19 whereby it can be manipulated. to open the jaws, the jaws being normally held together by a spring 20. The arm 17 is slightly resilient, having enough spring to it to permit it to be sprung over a hook 21 on the opposite side of the top bar 12 from the normal position of the clip, the clip being held in its normal position by a spring 22 which is arranged to bear on the arm 17 so that the arm is swung to the left whenever it is released. In practice the insert sheet of a piece of music 2% is secured near its outer end by the clip 18 and the arm 17 is then swung against the pressure of the spring 22 so that the arm is seated in the hook 21, the hook being open at the top.

On the top bar is a suitable eye 2st through which passes a rod 25, the rod preferably having a flange 26 on its top edge, the top end of the rod 25 being arranged in the eye 24 and being so disposed that it is under the arm 17 when it is in the dotted position shown in Fig. 1, that is, to the right, from which position the music is to be turned. The eye 24 is preferably made so that it can rotate in the bar 12. The lower end 27 of the rod 25 is screw-threaded and is screwed into a. collar 28 on the lever 29, the lever when the music is clamped in the clip 18 and is in the position shown in dotted outline in Fig. 1, and when the music is to be turned, a slight tap or blow on the finger-piece or handle 31 will cause the lever 29 to be tilted on its pivot 30, the rod 25 is forced upward, and in turn the upper end of the rod 25 pushes the arm 17 up sufliciently to have it clear the top edge of the hook 21, and the spring 22 is then free to swing the arm 17 to the position shown in full lines to the left of Fig. l and the music is turned.

In the case of a front panel that is provided with a shelf at the bottom, as shown at 33 in Fig. 5, I place the side bars against the front panel and suitable clamps, each consisting of a metal strip 3%, are placed so that the end 35 and the intermediate portion are on the bottom and top surfaces of the shelf 33, and a suitable set-screw 3T clamps the parts together. The upwardly projecting end 38 is provided with a setscrew 39 which bears against one side bar of the frame and holds it in place.

In Fig. 6 is illustrated a modified form of clamp which is employed when the shelf 40 is separate from the front panel s'l of the piano. In this case I use a J-shaped clamp one of the arms of which, as 43, is provided with a set screw ts, the end of which, with. a suitable washer is used to clamp the side bars to the frame of the piano or music stand. This leaf turner can be easily collapsed and easily set up, either operation taking but little time.

lVhen the device is to be assembled from the position shown in F 1, the rod 25 is unscrewed from the collar 28 and then swung in close to the top bar as shown in Fig. 2, the lever 29 can then be swung in alinement with the side bar 11, as is best illustrated in Fig. 2, and after having been unclamped from their support, the side bars 10 and 11 are swung on their pivot 13 and are alined with the top bar 12. it will thus be seen that when collapsed the turner provides a long, narrow ackage and is easily placed in the average music case or is easily carried in the hand.

The material of which the device is made is immaterial to its successful operation, since any suitable material can be us-d, but I prefer to make the side bars and the top bar of thin wood, and the arm 17 of spring metal and of a size calculated to make its bending somewhat easy so that its insertion into and its springing from the hook 21 is easily accomplished.

I prefer to cover the pin 16 with a shell. 1-6 which is slotted at 47, the slot -17 acting as a guiding means for the arm 17, the shell &6 protecting the spring 22 and acting, preferably, as a support or hearing for the pin 16. The shell 4-6 is usually secured by means of lips f? which are integral with the shell and are clamped over the top and bottom edges of the top bar.

Having thus described my invention, what I claim is 1. A music leaf turner consisting of a frame, the frame having a top bar and two side bars pivoted thereto in a manner to pcrmit their being swung substantially parallel with the top bar, a spring-actuated music leaf turning device on the top bar, means for restraining the action of the turning device, and manually operated means for forcing the turning device from the restraining means.

2. A music leaf turner comprising a frame, the frame having a top bar and side bars pivoted at their top ends with the top bar whereby the side frames can be swung on the top bar, a lever on one side frame, the lever having a handle thereon, a spring actuated music turning means on the top bar, means for restraining the turning means, and an operative connection between the turning means and the lever for releasing the turning means from the restraining means.

3. A music leaf turner comprising a. rame, the frame having a top bar and side bars swinging thereon whereby the bars can be swung together, a somewhat flexible arm swinging on the top bar, a spring for swinging the arm, means on the arm for grasping a sheet of music, a hook on the top bar into which the arm can be seated after it is bent, and manually operated means for bending the arm to release it from the hook.

4-. A music leaf turner comprising a frame, the frame having a top bar and side bars hinged at their top edges to the outer ends of the top bar whereby the bars can be swung together, a somewhat flexible arm swinging on the top bar, a spring for swinging the arm in. one direction, a paper-holding clip on the end of the arm, a hook to restrain the arm against being swung by the v spring, the hook bein s0 disposed that the arm must be bent on its entrance into the hook and lie unsprung therein, a lever pivoted to one of the side bars and having a handle thereon, and a rod secured to the lever with its upper end disposed under the arm whereby the lever and rod can be operated to bend the arm to release it from the hook.

5. A music leaf turner comprising a frame, the frame having a top l ar and side bars hinged at their top edges to the outer ends of the top bar whereby the bars can be swung together, a somewhat flexible arm s vinging on the top bar, a spring for swing ing the arm in one direction, a paper-hold ing clip on the end of the arm, a hook to restrain the arm against being swung by the spring, the hook being so disposed that the arm must be bent on its entrance into the 1 Oil hook and lie unsprung therein, a lever on one of the side bars, a handle on the lever, a rod arranged to slide and having its upper end disposed under the arm, and a detachable connection between the rod and the lever.

6. A music leaf turner comprising a frame, the frame having a top bar and side bars hinged at their top edges to the outer ends of the top bar whereby the bars can be swung together, a somewhat flexible arm swinging on the top bar, a spring for swinging the arm in one direction, a paper-holding clip on the end of the arm, a hook to restrain the arm against being swung by the spring, the hook being so disposed that the arm must be bent on its entrance into the hook and lie unsprung therein, a lever on one of the side bars, a handle on the lever, an eye arranged to be partly rotated on the top bar, a rod sliding in the eye and being so disposed that its upper edge is beneath the arm, the lower end of the rod being screw-threaded, and a screw-threaded collar on the lever into which the lower end of the rod can be screwed.

In testimony that I claim the foregoing I have hereunto set my hand this 15th day of May, 1913.

EDWARD HANDLER.
